Autodesk said it will buy BuildingConnected for $275 million, adding bid management, risk analysis and other preconstruction tools to the company's construction portfolio.

Autodesk also announced it completed the previously announced $875 million acquisition of PlanGrid, a provider of construction productivity software.

BuildingConnected helps real estate owners and general contractors find and hire contractors for their projects. Customers include Turner Construction, McCarthy, Mortenson, StructureTone, Skanska, Clark Construction, Ryan Companies and AECOM.

Autodesk CEO Andrew Anagnost said that the acquisition, along with Autodesk BIM 360, Revit, AutoCAD, and PlanGrid and Assemble Systems, expands its offering for the construction sector.

BuildingConnected offers TradeTapp, a subcontractor risk analysis platform, and Bid Board Pro, a platform that helps subcontractors manage bids.

The deal is expected to close in January 2019.
